. Be it known that 'I, ARTHUR. J. BAZELEY,

of Cleveland, Cuyahoga county, Ohio, have invented a new and useful Improvement in 5 Car;Couplers, of. which the'following is a full,-clear,:an d exact description, reference being had to the. accompanyin drawings, forming part of this speci cation,- in

which 'Fi ure 1 is a side view of the locking mom er; Fig. 2 is a transverse vertical sec tion of a coupler head with the locking member therein and shown in the knuckle-thrown position; and Fig. 3 is a horizontal longitudinal section showing the locking member in the lockset position.

My invention has relation to certain new and useful improvements incar couplers, and more particularly to the locking: and

opening member or piece of the coupler.

The present application'is a continuation of my ending application Serial N 0. 468,418, fi ed December 21st, 1908.

The object of the invention is to provide 25 a car coupler of the automatictype with a combined lock and knuckle-throw ng member or piece of novel character having.

means for holding it in its lockset position on the bottom wall of the chamber of the coupler head.

In the accompanying drawings, the' numeral 2' designates a coupler head having an opening 3 in its bottom wall. The locking and opening member consists of a looking as head 4, a rearopening member 4, and an intermediate connecting member 4" having 111 its upper surface a groove or depression 4 which is arranged to fulcrum, when the piece is lifted, against a projection 2". 'on- 40 the upper wall of the coupler head. The I lookingand opening member or piece is also provided with the eye 5 for engagement with a suitablelifting device 8.

When in. locking position in the coupler.

46 head, this locking and o ening piece extends over the tail of the muckle, the head 4. fitting in front of the k'nuckle'tail and thus locking the same in position. WhenQit is desired to release the knuckle and to lock- 0 set thelock, the piece is raised until the rear end of the member 4 is withdrawn from the hole 3 in "the floor of the coupler andthe accessible.

groove 4 comesinto' engagem'ent' with the fulcruming projection 2". The lower end of the member 4 is thereby moved or swung in a direction which is forward relatively to the drawbar, being thereby brought over and caused to rest upon the ledge or seat 6,

which is justforward of the hole 3, and whereby said piece is held in its unlocked and lockset position. In order to permit the member 4: to rest fully upon this lockset shelf or ledge closeup against theadjacent wall of the coupler head, so that it cannot easily be dislodged therefrom by an accidental jar or shock, it is desirable to cut .away the side of said member, as shown at 4, thereby forminga recess which is adapted, in thelockset position of said member, to coiipe'rate with the correspondingly shaped'pro ction 7 onthe adjacent wall'of the coupler head. This projection ,7 forms a part of'the coupler wallwhere, for purposes 7 of strength, all the metal possible is needed. Therefore, any cutting of the wall at this point would result in aconsiderable loss of strength and isto be avoided, if possible.

cent to this projection and owing to the proximity of theprojection is relatively in- There is some difficulty, therefore, in roviding for the proper seating of the mem 'er 4; upon this shelf. By providing said member with the reentrant recess 4 the locking-member is permitted to hug the coupler wall very closely while' in lockset position because the projection Tenters 'The lockset ledge or seat (5 is closely adjathis reentra-nt recess and permits the leg 4:

to lie closely-against the projection. The

crum projection 2, thereby caus ng. the lock mg and opening member 4 to come in contact with the tail 9 of the knuckle and throw the knuckle to its open position. This position of the locking and opening memberis shown in Fig. 2.
